摘要:
The design of a 5 GHz phase-locked loop (PLL) with a phase-adjusting function is presented. The voltage-controlled delay line (VCDL) is proposed to adjust the feedback signal phase by an externally controlled voltage. The output phase difference of multi-PLLs can be shifted from 0(?) to 98.6(?), when the propagation delay of VCDL is 0.41 and 4.75 ns, respectively. The proposed PLL was fabricated in TSMC 0.18-mu m CMOS process and supplied at 1.8 V with a power dissipation of 16.38 mW. The locking time is less than 2 mu s under the different controlled voltage ranges of VCDL.
